Those three are located in North Las Vegas or Henderson, though. The list is for Las Vegas casinos. There are a number of others if you want to include Henderson, like Green Valley Ranch.

Of course, many of the casinos on Las Vegas Blvd aren't in Las Vegas at all, but in Paradise, NV.

This has a catch as well, Paradise is not an incorporated town, but a "census designated place" in Clark County. If it were a town, it would be one of the largest cities in Nevada! The USPS calls the zip codes in Paradise 'Las Vegas'. However, search for Bank of America branches in Las Vegas, you won't find those in Paradise listed. One of the paradoxes associated with a rapidly growing town.
